tail

I don't know if there's any? but is php built in web server also save its error logs in a file? for tailing purposes, like when creating virtual host in apache. UPDATE: i'm using mac osx thenickdude The built-in webserver doesn't log anywhere by default, so you need to provide a php.ini for it to customise this. For example, if you created a file called php.ini with this content: error_log = /Users/me/test.log log_errors = on date.timezone = UTC Then you can start PHP's built-in webserver like this: php -S 127.0.0.1:8080 -c php.ini And error_log() calls will be logged to the file you've

I am working on a shell script with exiftool to automatically change some exif tags on pictures contained in a certain folder and I would like to use the output to get a notification on my NAS (a QNAP) when the job is completed. Everything works already, but - as the notification system truncates the message - I would like to receive just the information I need, i.e. the last line of the shell output, which is for example the following: Warning: [minor] Entries in IFD0 were out of sequence. Fixed. - 2015-07-12 15.41.06.jpg 4512 files failed condition 177 image files updated The problem is that

while using dplyr i'm having trouble changing the last value my data frame. i want to group by user and tag and change the Time to 0 for the last value / row in the group. user_id tag Time 1 268096674 1 3 2 268096674 1 10 3 268096674 1 1 4 268096674 1 0 5 268096674 1 9999 6 268096674 2 0 7 268096674 2 9 8 268096674 2 500 9 268096674 3 0 10 268096674 3 1 ...

I've tried to do something like this,

We have several application servers, and a central monitoring server. We are currently running ssh with "tail -f" from the monitoring server to stream several text logfiles in realtime from the app servers. The issue, apart from the brittleness of the whole approach is that killing the ssh process can sometimes leave zombie tail processes behind. We've mucked around with using -t to create pseudo-terminals, but it still sometimes leaves the zombie processes around, and -t is apparently also causing issues elsewhere with the job scheduling product we're using. As a cheap-and-dirty solution

I have a log file and want to create a webpage (possibly Python but not strictly) that will work much like unix "tail -f filename" command works (show new log lines when they are written to file). So that user will continuously see log right in browser. How would you implement this? Tailon is a python webapp that, among other things, provides tail -f like functionality. In addition, wtee (a sister project of tailon) can make all its stdin viewable in the browser - its use is identical to the unix tee command: tail -f filename | wtee Scullog , having capability of sharing the local drive to the
